AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MOBILE AL
138 PM CDT SAT APR 5 2014

.AVIATION UPDATE [05.18Z KMOB/KBFM AND KPNS TAF ISSUANCE]...MVFR CIGS
ARE EXPECTED TO PERSIST ACROSS THE LOCAL TERMINALS THROUGH THIS
AFTERNOON IN THE WAKE OF A COLD FRONT THAT REMAINS STALLED OFFSHORE.
RAIN IS EXPECTED TO INCREASE IN COVERAGE ALONG THE COAST LATER THIS
AFTERNOON...WITH CONTINUED POTENTIAL FOR LIGHT RAIN SHOWERS OR
DRIZZLE THROUGHOUT THE NIGHT. CIGS MAY LOWER TO IFR LEVELS LATE
TONIGHT INTO EARLY SUNDAY MORNING...WITH A FEW THUNDERSTORMS POSSIBLE
SUNDAY MORNING...AFTER 06.12Z. /22

&&

.PREV DISCUSSION... /ISSUED 624 AM CDT SAT APR 5 2014/

..HEAVY RAIN AND SEVERE STORMS WILL BE OF POTENTIAL IMPACT ACROSS
THE REGION LATE THIS WEEKEND INTO EARLY MONDAY...

SHORT TERM...(TODAY THROUGH MONDAY)...TODAY THROUGH TONIGHT...
REGIONAL SURFACE OBSERVATIONS SHOW THAT A COLD FRONT HAS PUSHED
OFFSHORE...AND ROUGHLY STRETCHES FROM FAR SOUTHEASTERN LOUISIANA
THROUGH OUR NORTHERN GULF MARINE ZONES AS OF 4 AM CDT. THIS BOUNDARY
HAS SERVED AS FOCUS FOR SCATTERED TO NUMEROUS SHOWERS AND
THUNDERSTORMS WELL OFFSHORE EARLY THIS MORNING. THE SCATTERED
CONVECTION THAT DEVELOPED OVER SOUTHEAST MISSISSIPPI AND SOUTHWEST
ALABAMA LATE LAST EVENING GRADUALLY DISSIPATED...AND RADAR CURRENTLY
SHOWS NO ECHOES OVER INTERIOR AREAS...BUT THAT IS EXPECTED TO CHANGE
BEGINNING LATER THIS MORNING.

THE FRONTAL BOUNDARY WILL REMAIN STALLED OVER THE OFFSHORE WATERS
TODAY...WITH NORTHEASTERLY SURFACE FLOW AND SLIGHTLY COOLER
TEMPERATURES/LOWER DEWPOINTS FILTERING ACROSS OUR FORECAST AREA
BEHIND THIS FEATURE. HOWEVER...A MOIST ZONAL FLOW PATTERN ALOFT WILL
PERSIST ACROSS MUCH OF THE CENTRAL GULF COAST REGION TO THE NORTH OF
THE BOUNDARY TODAY. AN EMBEDDED SHORTWAVE IMPULSE LIFTING
NORTHEASTWARD TOWARD THE REGION WILL RESULT IN INCREASED DEEP LAYER
MOISTURE AND LIFT ACROSS MUCH OF THE FORECAST AREA TODAY...
ESPECIALLY ACROSS LOCATIONS GENERALLY ALONG AND TO THE SOUTH OF THE
U.S. HIGHWAY 84 CORRIDOR. WE THEREFORE EXPECT INCREASING COVERAGE OF
SHOWERS AND THUNDERSTORMS ACROSS THESE LOCATIONS LATE THIS MORNING
AND THIS AFTERNOON. THE LATEST HIGH RESOLUTION SOLUTIONS CONTINUE TO
SHOW THE BEST COVERAGE NEAR THE COAST TODAY WITHIN THE DEEPEST
MOISTURE AXIS...AND WE WILL TREND POPS HIGHEST ACROSS THIS AREA.
AT LEAST SCATTERED CONVECTION MAY DEVELOP NORTHWARD TOWARD THE
HIGHWAY 84 CORRIDOR THIS AFTERNOON.

SURFACE LOW PRESSURE WILL DEVELOP IN THE VICINITY OF THE FAR WESTERN
GULF/DEEP SOUTH TEXAS VICINITY LATE TONIGHT...WHILE THE ASSOCIATED
BOUNDARY OVER THE NORTHERN GULF BEGINS TO LIFT NORTHWARD AS A WARM
FRONT OVER THE NORTHERN GULF WATERS THROUGH EARLY SUNDAY MORNING.
THE AXIS OF DEEP LAYER MOISTURE ALSO LIFTS NORTHWARD AND BECOMES
ORIENTED ACROSS INTERIOR PORTIONS OF THE FORECAST AREA OVERNIGHT.
SHORT RANGE SOLUTIONS ARE IN AGREEMENT WITH CONVECTION BECOMING
FOCUSED FROM INTERIOR SOUTHEAST MISSISSIPPI AND SOUTHWEST/SOUTH
CENTRAL ALABAMA WITHIN THIS AXIS LATE TONIGHT. WE HAVE TRENDED THE
HIGHEST POPS /NEAR CATEGORICAL COVERAGE/ AND QPF OVER INTERIOR AREAS
TONIGHT. HEAVY RAINS THAT FALL TONIGHT WILL SET THE STAGE FOR
POTENTIAL FLOODING PROBLEMS/RIVER RISES AS ADDITIONAL HEAVY RAINS
MOVE IN LATE SUNDAY INTO EARLY MONDAY. LATER SHIFTS WILL EVALUATE
THE NECESSITY OF A FLASH FLOOD WATCH. /21

SUNDAY...AS THE UPPER SHORTWAVE TROUGH MOVES FROM OVER THE DESERT
SOUTHWEST TO OVER THE SOUTHERN PLAINS...IF FORMS A SURFACE LOW OFF
THE TX COAST AND MOVES IT NE...TO OVER THE SABINE RIVER BY SUNDAY
EVENING. THIS SHIFTS SURFACE WINDS TO SE ACROSS MOST OF THE FA AS THE
BOUNDARY OVER THE GULF ORGANIZES INTO A WARM FRONT AND BEGINS TO
MOVE INLAND OVER THE LA COAST. ISENTROPIC UPGLIDE PRECIP CONTINUES
OVER MAINLY NW-ERN SECTIONS OF THE FA AND POINTS NW. AT THIS
POINT...AM NOT EXPECTING SEVERE WEATHER...THOUGH WATER PROBLEMS MAY
BEGIN TO SHOW THEIR HEAD. QPF AMOUNTS RUN IN THE 1-1.5 INCH RANGE
OVER NW-ERN PORTIONS OF THE FA FOR SUNDAY...AND WITH SOUTHERLY FLOW IN
FULL AFFECT...AMOUNTS FOR THE DAY MOST LIKELY WILL GO UP LOCALLY WITH
TRAINING TSRA THE CAUSE.

SUNDAY NIGHT...AS THE UPPER TROUGH SWINGS EAST ACROSS THE SOUTHERN
PLAINS...THE SURFACE LOW ACCELERATES NNE ACROSS THE MISS RIVER
VALLEY...DEEPENING AS IT GOES. LOW LEVEL FLOW INCREASES...WITH THE
WARM FRONT MOVING NORTH ACROSS THE LOWER MISS RIVER VALLEY...THE
WESTERN PORTIONS OF THE SOUTHEASTERN CONUS AS A POST SYSTEM COLD FRONT
ORGANIZES. EAST OF THE COLD FRONT...MODELS SOUNDING SHOW INSTABILITY
GETTING INTO THE 1000-1500J/KG RANGE AND HELICITIES ABOVE 250
M^2/S^2. SPC HAS PLACED THE ENTIRE FA UNDER A SLIGHT RISK FOR SEVERE
WEATHER. ANY STORMS THAT BECOME STRONG TO SEVERE ARE EXPECTED TO
CONTAIN DAMAGING WINDS AND LARGE HAIL...WITH A POSSIBILITY OF
TORNADOES AS A RESULT.

MONDAY...THE UPPER DYNAMICS MOVING ACROSS THE PLAINS GET A
NORTHEASTWARD PUSH AS THEY PUSH AGAINST AN UPPER RIDGE ALONG THE EAST
COAST. THE SURFACE LOW CONTINUES IS NNE-WARD TREK...AND THE SURFACE
FRONT MOVES ACROSS THE FA. THE AREA CLEARS OF PRECIP FROM THE WEST. A
CHANCE OF WATER AND SEVERE WEATHER EXISTS INTO EARLY MONDAY
MORNING...BUT WITH THE UPPER DYNAMICS MOVING OFF...AND THE SURFACE
LOW'S DEEPENING EASING...THE LOW LEVEL FLOW WEAKENS QUICKLY AND THE
RISK LESSENS QUICKLY.

FOR THE FORECAST...TEMPS ABOVE SEASONAL...WELL ABOVE AT NIGHT ARE
IN THE FORECAST.

LONG TERM...(MONDAY NIGHT ON)...UNSEASONABLY COOL AIR MOVES OVER THE
FA BEHIND THE FRONT. GUIDANCE HAS BEEN CONSISTENTLY ADVERTISING POST-
FRONTAL STRATUS AND SHRA OVER MAINLY NORTHERN SECTIONS OF THE FA
LATE MONDAY NIGHT THROUGH TUESDAY. TEMPS FALLING INTO THE LOWER 40S
OR UPPER 30S IN SOME LOCALITIES ARE LIKELY TUESDAY NIGHT AS WINDS
SETTLE AS SURFACE HIGH PRESSURE MOVE OVER AND EAST OF THE FA THROUGH
MID WEEK.

THE LATTER HALF OF THE WEEK...WITH THE SURFACE HIGH PUSHING TO THE
EAST COAST...SOUTHERLY FLOW RETURNS TO THE FA AND MOISTURE LEVELS
INCREASE INTO THE WEEKEND. TEMPS ALSO MODERATE UPWARD INTO THE
WEEKEND.

MARINE...A COLD FRONT HAS PUSHED OFFSHORE EARLY THIS MORNING AND IS
EXPECTED TO REMAIN STALLED OVER THE NORTHERN GULF MARINE ZONES
THROUGH TONIGHT. NUMEROUS SHOWERS AND THUNDERSTORMS WILL CONTINUE TO
DEVELOP ALONG THIS BOUNDARY TODAY...A FEW OF WHICH COULD BE LOCALLY
STRONG. THE BOUNDARY WILL LIFT NORTHWARD AS A WARM FRONT ON SUNDAY AS
LOW PRESSURE DEVELOPS OVER THE WESTERN GULF AND TRACKS NORTHEAST INTO
THE TENNESSEE VALLEY BY MONDAY MORNING. STRONG TO SEVERE STORMS ARE
POSSIBLE OVER THE COASTAL WATERS SUNDAY NIGHT. STRENGTHENING ONSHORE
FLOW MAY RESULT IN HAZARDOUS CONDITIONS FOR SMALL CRAFT LATE SUNDAY
INTO MONDAY. A COLD FRONT WILL PUSH THROUGH THE MARINE AREA MONDAY
NIGHT. HAZARDOUS CONDITIONS FOR SMALL CRAFT APPEAR LIKELY TUESDAY
INTO WEDNESDAY AS STRONG OFFSHORE FLOW AND BUILDING SEAS ARE EXPECTED
IN THE WAKE OF THE FRONTAL PASSAGE. /21
